Recent findings Since December 2016, the United States Food and Drug Administration has approved four drugs for six different ovarian cancer maintenance indications based on the results of clinical trials demonstrating efficacy and tolerability. These include antiangiogenesis and poly (adenosine diphosphate-ribose) inhibitors (PARP inhibitors). Four drugs are approved for use in maintenance therapy for recurrent ovarian cancer, including bevacizumab (GOG-0213 and OCEANS), niraparib (NOVA), olaparib (Study 19 and SOLO2) and rucaparib (ARIEL3). Two drugs are approved for use in maintenance therapy in newly diagnosed ovarian cancer, including bevacizumab (GOG-0218) and olaparib (SOLO1). New data were reported at the European Society for Medical Oncology Congress in October 2019 that may lead to the approval of additional strategies in front-line maintenance, including the use of niraparib (PRIMA), veliparib (VELIA) and bevacizumab + olaparib (PAOLA). Summary The landscape of maintenance treatment options for ovarian cancer has been rapidly expanding and continues to evolve as new data emerge. Currently approved strategies include antiangiogenesis and PARP inhibitor treatments. Copyright © 2020 YEAR Wolters Kluwer Health, Inc. All rights reserved.
